Abstract:

ICA is the application of very promising methods in the field of signal processing. While the effective separation and identification of the fMRI sign  als is a technical field which is being studied and experimented. In recent years, ICA has been successfully used in the fMRI data processing. It has become a very effective way of analyzing the fMRI data. The paper introduces the application of ICA both in the analysis of the fMRI data and a variety of algorithms in the blind source separation of the fMRI signals. It also analyzes the problems existing in three algorithms, and presents the prospect of  research in this field.
